Main Description

Meet the Easun Power Hybrid Off-Grid Solar Inverter Charger ISolar-SMG-II series, a versatile solution for clean, reliable power in both off-grid and backup scenarios. These compact units deliver a pure sine wave 230V AC output with intelligent MPPT solar charging, making them ideal for homes, cabins, or remote installations powered by solar arrays.

Available in three configurations to match your battery bank and solar setup: 2KW at 12V, 3.2KW at 24V, and 4KW at 24V. Each model combines MPPT charging, multiple output priorities, and Lithium battery activation options to fit a wide range of energy systems. The 3.2KW and 4KW variants can even operate without a battery when photovoltaic input is sufficient, while the 2KW model requires a battery for operation.

Key features include built-in MPPT (60A/100A/120A depending on model), compatibility with LiFePO4 batteries via RS485, and a detachable dust cover for harsh environments. WiFi remote monitoring is optional, and the unit supports multiple output priorities (UTL, SOL, SBU, SUB) plus an EQ function to optimize battery performance and extend lifecycle. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.

Whether you’re powering a tiny off-grid cabin or providing backup for essential loads, these inverters are designed to adapt to your solar array, battery choice, and daily power needs.

Benefits & Tips

  • Optimal for lithium-based systems: lithium activation by PV (or PV/Utility on higher models) with RS485 communication to LiFePO4 batteries.
  • Maximize solar gains: the MPPT charger handles high PV voltages and currents, enabling efficient charging even on cloudy days.
  • Smart power management: use output priority settings (UTL/SOL/SBU/SUB) to protect critical devices during outages and extend battery life with the EQ function.
